A constructor that initializes this EObjectAttributeValueCondition with the passed values. It defaults to using ConditionPolicy.ANY for the ConditionPolicy policy, the PruneHandler.NEVER for the PruneHandler and the sets resolving to true

Parameters:

attribute - The EAttribute whose value is to be tested

valueCondition - the Condition object to use for evaluating the EAttribute value

eStructuralFeatureValueGetter - The IEStructuralFeatureValueGetter used to extract the value of the EAttribute from a given context object

EObjectAttributeValueCondition

public EObjectAttributeValueCondition(EAttribute attribute,
                                      Condition valueCondition)

The default EStructuralFeatureValueGetter will be used when accessing the value of the EObject's attribute.

Parameters:

attribute - The EAttribute whose value is to be tested

valueCondition - the Condition object to use for evaluating the EAttribute value

valueCondition - the Condition object to use for evaluating the EAttribute value

eStructuralFeatureValueGetter - The IEStructuralFeatureValueGetter used to extract the value of the EAttribute from a given context object
